项目摘要
To understand how cells develop or function, it is important to study equivalent cells across individuals.
Comparing a cell's fate between mutant and wild-type individuals can reveal how a gene regulates
development. Similarly, combining information about a neuron's structure from one animal with functional
recordings of its activity in another can reveal that neuron's contribution to a circuit. Comparing information
across animals requires identifying cells by some combination of cell shape, position, gene expression and
lineage. However, methods to identify cell fates in complex tissues are simplex, focusing on one or a small
number of cell types at a time, making it hard to assess the behavior of the full population. We propose to
develop multiplexed 3D multicolor fluorescent labeling and associated hardware and software to
automate cell identification in live animals. In Aim 1 we will develop this approach in the nematode C.
elegans because its invariant developmental lineage and known wiring of every neuron provides a powerful
platform on which to build, test and validate this approach. In Aim 2 we will apply this to understand patterns of
fate transformations across the entire organism in developmental mutants. Finally in Aim 3, we will use our
labeling method to identify all neurons in the adult nerve ring (brain), and combine this with whole-brain
imaging methods to map for the first time activity of every neuron onto the wiring diagram.
